Wurth Elektronik WE-CMB Common Mode Choke 14mH 4A
Wurth Elektronik WE-CMB common mode choke, 14mH, 4A. Compact design for high interference suppression and power management.
The Wurth Elektronik WE-CMB Common Mode Choke achieves high suppression of asymmetric interferences, even at low frequency ranges. During the development of the WE-CMB series, a primary focus was placed on reducing the often underestimated parasitic effects associated with common mode chokes, ensuring superior performance and reliability in your circuits.
Featuring a perfectly balanced core-to-winding ratio, this component enables very high currents at comparable areas while maintaining sufficient inductance. The adjusted wire gauge realises low heating during operation, which is critical for maintaining efficiency and longevity. Additionally, the low capacitance winding technique provides excellent broadband screening.
The choke boasts a very compact design, offering the highest possible current for its small size. It ensures high interference compression for asymmetric interference rates across the frequency spectrum. With an impressive operating temperature range, it is built for demanding environments and critical applications.
